Furthermore, in one embodiment, the inner side of the buckle outer part 10 opposite to the buckle inner part 20 is provided with protrusions 21, and the outer side of the buckle inner part 20 opposite to the buckle outer part 10 is provided with grooves. The groove 11 covers partially or entirely the outer side of the buckle inner 20 opposite the buckle outer 10. When the buckle inner 20 rotates (or the buckle outer 10 rotates), the protrusion 21 is switched from the engagement with one of the grooves 11 to the engagement with the other groove 11.
In order to make the rotation controllable, in one embodiment, the grooves 11 are uniformly distributed on the outer side surface of the inner buckle part 20 opposite to the outer buckle part 10, and are in a wave-shaped tooth shape as a whole. Of course, the distribution of the grooves 11 may be close or arranged at regular intervals, equidistant or non-equidistant, etc., according to different practical needs.

In one embodiment, the outer snap part 10 comprises an inner elastic wall 12 and an outer sheath 13 arranged in sequence from inside to outside, the inner elastic wall 12 being located between the outer sheath 13 and the inner snap part 20. In order to increase the elastic effect, a gap is formed between the elastic inner wall 12 and the outer sheath 13, and the protrusion on the snap outer part 10 is positioned on the inner side surface of the elastic inner wall 12. If a torque is applied to the snap outer 10 or the snap inner 20, and the torque is larger than a certain area value, the elastic inner wall 12 of the snap outer 10 is elastically deformed, and the protrusion 21 of the snap outer 10 slides relative to the groove 11 of the snap inner 20 to engage with the next groove 11 of the snap inner 20. In one embodiment, the inner flexible wall 12 and the outer sheath 13 may be integrally formed.
In one embodiment, the outer buckle part 10 and the inner buckle part 20 are a pair of semicircular rings that can be opened and closed around a shaft, and the shaft end and the open-close end are oppositely arranged on the semicircular rings, and the open-close ends are connected through a buckle. The inner clip member 20 is connected to the wire harness by means such as the inner clip member 20 facing the snap-fit feature, and has a requirement that the inner clip member 20 facing the snap-fit feature should be moved with respect to the wire harness axis to a certain force value range. The opposing snap features may be, and are not limited to, snap connections in this embodiment. If a complete circular ring-shaped buckle inner part is used, the inner diameter of the buckle inner part is smaller than the outer diameter of the cable, so that the cable is clamped.

The desired rotational sound can be accommodated by selection of the material of the intermeshing asperities, for example, a relatively crisp sound can be achieved by co-rotation between a pair of plastic materials, and a relatively low motion sound can be achieved by co-rotation of plastic with rubber or polyurethane type members. In one embodiment, the concave-convex part is made of plastic, and can give out a crisp prompt sound to remind that rotation occurs.
In one embodiment, the outer surface of the snap outer 10 is provided with an indicator, which indicates the direction and angle of rotation of the snap inner 20, or the snap outer 10. The indicia may be, but is not limited to, arrows and numerical scales. The markings are provided on the outer surface of the snap outer part 10 for easy viewing and may be provided elsewhere if desired.
In one embodiment, the outer side of the snap outer 10 is provided with a limiting plate 15 to limit the relative movement of the snap outer 10 to the snap inner 20 along the wire harness direction.
